^ Sigh. Of course I tried searching before posting. Does it make you feel so important when posting that reply? oh your such a big boy! I wanted advice not some stupid no one to complain about my post.
Anyways I will share my solution which helped me a lot ^_^:
Currently my save game is.... 35mb (from 500mb)!!! With my WHOLE sims population! And it takes less than 2 mins to save.I found using the NRAAs Porter to be of much use. http://nraas.wikispaces.com/PorterThis mod helps you to transport sims and numerous households at a time across to different worlds.
I moved my whole sim population at a third of a population at a time to my newly made world. The move included the sim's inventory, lifetime points/rewards, jobs and relationships between the sim's that have been grouped together when moving. I'm not quite sure about the family tree working properly on the move however.
The downside is that you have to use a completely new world, however you can easily just save a certain lot from you old world that you want to keep by saving the lot and placing it in the new world.
And since I moved the population in 1/3's at a time to the new world I lost the sim's relationship between the other sims that have not moved within the same 1/3 population at a time.
You also need to make sure you have enough lots for sims to move in or you will be stuck with a lot with 50 sims and
you won't be able to move them out!I have crashed a few times as well trying this method, mainly by trying to go back to main menu from playing a saved world.
Note: ALWAYS back up your saves in another folder before trying this out as it could stuff up your game.
Do this at your own risk! I am not responsible for you if you try this method.And to keep the save size low, try not to play all the households in your sim world.

Other stuff I tried:
*** Deleting Cache, it didn't do anything for me (I tried it but didn't mention it before because I didn't think it was too relevant ...I am now adding it just to clarify)
***Going into the save folder and deleting theTravelDB and other (China, Egypt, France)DB... this didn't make a difference to the saving time at all for me.
***Using TS3 Recompressor (
http://www.moreawesomethanyou.com/smf/index.php/topic,15129.0.html) the s3rc function helped get rid of about 30mb and the time on the save didn't make much difference, however if you have a smaller save file it will most likely be a significance to you.
+ I did not try the decrapify function as I was unsure of the risk it came with and it seemed a bit complicated fiddling with mods.
